Dear John by Nicholas Sparks

Description

An angry rebel, John dropped out of school and enlisted in the Army, not knowing what else to do with his life until he meets the girl of his dreams, Savannah. Their mutual attraction quickly grows into the kind of love that leaves Savannah waiting for John to finish his tour of duty, and John wanting to settle down with the woman who has captured his heart.

But 9/11 changes everything. John feels it is his duty to re-enlist. And sadly, the long separation finds Savannah falling in love with someone else.
